Currently, most photosensitive hydrogels are suitable for skin wounds, and generally ultraviolet light curing devices can complete the curing. With the continuous development of photosensitive hydrogels, many of them have been used for in vivo wound repair. However, the common ultraviolet curing devices are not suitable for working in the human body cavity. Therefore, this field urgently needs to develop a curing device suitable for working in the human body cavity. Utility Model Content

[0026] like Figure 1-6 As shown, the present disclosure provides an intracavity light curing device, which is composed of an optical fiber 1, a housing 2, a portable light source 3 and a light cone 4. One end of the optical fiber 1 is connected to the light cone 4, and the portion where the optical fiber 1 and the light cone 4 are connected is arranged inside the housing 2, and the light cone 4 is also arranged inside the housing 2; one end of the housing 2 is connected to the portable light source 3, and then the optical fiber 1, the light cone 4, the housing 2 and the portable light source 3 cooperate in sequence to form the intracavity light curing device of the present utility model. The housing 2 is connected to the portable light source 3, and the light cone 4 inside the housing 2 cooperates with the portable light source 3 and couples the light source. The coupled light source enters the optical fiber 1 and is transmitted to the head end of the optical fiber for light curing. The light cone 4 is composed of a light cone outer shell 41 and a light cone inner core 42 located in the light cone outer shell 41. The optical fiber terminal 13 arranged at one end of the optical fiber 1 is connected to the light cone outer shell 41. The outer shell 2 is composed of a left outer shell and a right outer shell, which is convenient for the installation and disassembly of the optical fiber 1 and the light cone 4. The portable light source 3 is commonly available on the market, and different specifications can be selected as needed. A light source switch 31 is also provided at the front end of the portable light source 3, which can be controlled at any time when light curing is required, and the portable light source 3 and the outer shell 2 can be connected by a spiral or snap connection, and the assembly and structure are simple, and the operation is also convenient.

[0027] In some specific implementations, such as Figure 3 and 4 As shown, the optical fiber 1 is composed of a sheath tube 11, an optical fiber core 12 and an optical fiber terminal 13. The sheath tube 11 completely wraps the optical fiber core 12, and the optical fiber terminal 13 is connected to the sheath tube 11 at one end. The optical fiber core 12 extends from the sheath tube 11 and passes through the optical fiber terminal 13; wherein the optical fiber core 12 can be composed of a single thicker optical fiber core 12 or multiple thin optical fiber cores 12, and the end of the optical fiber 1 that is not connected to the optical fiber terminal 13 is the end that directly irradiates the wound surface, and the purpose of curing can be achieved after the light source is transmitted to this end. At the same time, the end faces of the optical fiber terminal 13 and the optical fiber core 12 are polished and flush, which can better couple the light source for transmission.

The portable light source 3 is detachable and can be assembled with different specifications or light sources according to the needs of the operation. The light source switch 31 is arranged at the front end, which is close to the end held by the medical staff for easy operation. After turning on the light source switch 31, the light emitted by the light source 32 enters the light cone 4 and is coupled into the optical fiber 1, and then transmitted to the far end of the optical fiber 1 for light curing. At the same time, the portable light source 3 is connected to the housing 2 in a spiral or snap-on manner, which is simple to assemble and easy to replace.
